Live installer fails on numerous machine configs while trying to copy root files from dvd .
Hello vircobum,
Welcome here in the community of openSUSE users.
Please note that we are openSUSE users like you and sometimes we need some more information before we understand how we can help other openSUSE users.
I Googled for Edulife and found several sites all over the world, but I failed to see what the connection with openSUSE is. Now there are several possibilities, one of them that thiis is completely due to my ignorance.
But when you think that a bit of clarification about what you have, what you are doing and where you got stuck in that process might help people to help you, please do so.
I think he is talking about this https://news.opensuse.org/2013/05/08/announcing-the-release-of-opensuse-edu-li-f-e-12-3-1/
did you hash check the downloaded iso ?
Aha!!
But of course Edu Li-f-e is not the same as Edulife. Spelling is important in the computer world 
This is how i did hash check on DVD before trying it live from a usb

I only installed on one machine, but it worked fine there. I did boot successfully (using a USB rather than DVD) on another machine. I’m assuming that you are referring to “openSUSE-Edu-li-f-e-12.3-1-i686.iso”.
It’s hard to know what went wrong in your case, without more information.
